BAND, WHEEL.

Application. filed May 10,

To all whom it may concern:

Be it known that we, O'r'ro Kinnnn and JoHN T. Scorr, citizens of the United States, residing at Los Angeles, county of Los Angeles, State of California, and Sierra Madre Camp, in the county of Los Angeles and State of California, respectively, have invented new and useful Improvements in Band \Vheels, of which the following is a specification.

Although our present invention is referred to as a steel band wheel, itshould be understood that this invention. comprises not only a novel. band wheel, suitable for use in connection with oil derricks or elsewhere, but also a combination of such a band wheel with a tug rim; and our invention comprises also novel means: for suitably securing all parts of the mentioned organization relatively to one another. I

It is an object of our invention to provide a band wheel whose rim. is formed of channel irons, suitably deformed and adapted to produce a. crown; and we prefer to form the spokes also of channel irons suitably out, shaped and spaced, and. optionally associated with means for the retention of a tug rim, which may be of a usual or any preferred design; and we may manufacture our wheel and tug rim as an entirety or we may optionally adapt all of the parts of our wheel to be assembled upon ashaft already in position.

It is an object of our invention to associate a split hub, preferably provided with keyways adapting it to be secured to a shaft, with cheek plates, which may be so drawn together by transverse bolts as to wedge tightly against and firmly secure the parts of said split hub; the respective sections of said hub being provided with openings, or with notches, for transverse bolts adapted to cooperate in a locking of all parts rigidly together and in a transmission. of power therethrough.

Broadly, the objects of our invention include the economical production of band wheels of a novel and superior type; said wheels preferably comprising a novel rim, a novel hub and novel spokes, and novel connecting means, the specific objects of various sub-combinations being indicated in the following description of a preferred embodi- 1923. Serial No. 637,349.

ment of our invention, and the appended claims, taken inconnection with the accompanying drawings, in which Figure 1 is an elevation of a band wheel of our preferred design, a tug rim being associated therewith.

Fig. 2 may be regarded as a top plan view of the same, with parts broken away.

Figs. 3 and 4 are detail views, taken at right angles one to another, with parts broken away,and showing a preferred hub construction, as hereinafter described.

Referring in detail to that form of our invention which we have chosen for illustration, 1 is the rim of a wheel, shown as formed from a plurality of arcuate sections of channel iron, the channel iron being lat-- erally deformed, as by means of a bulldozer, in such manner as to produce an inward inclination of one of the flanges of the channel iron and a corresponding and substantially parallel outward inclination of the other flange thereof, a complete rim being formed by securing together the inwardly inclined flanges 2 of a plurality of rims, preferably in such manner as to form. a crown 3 at the center thereof. The outer flanges i may advantageously be provided with gusset plates 6, or they may be secured directly to the spokes 7, preferably also formed of channel irons, and secured. respectively to cheek plates 8, which are adapted to engage and retain the hub sections 9, 10, which may be provided with keyways 11, 12, or with other means for securing the entire organization to a shaft.

Although the spokes 7 may be of any preferred design, we prefer to render the ends interchangeable by providing such openings therein as shall adapt either end of a spoke to be secured to the mentioned rim and also to a tug rim 13, which may be of any usual or preferred design, and may be retained by clips 14., secured by means comprising bolts 15, shown as extending between respective pairs of spokes, and as provided with spacers 16, an additional short bolt 17 being additionally passed through each spoke and adjacent clip, in the manner best shown in Figure 2.

Although we may use any preferred number of arcuate sections in the formation of a rim, we find it advantageous to employ bolts 19, passing therethrough; and when a Wheel 'of our preferred design is not to be built in situ, the respective semicircular sections may be so assembled, in the manner suggested in the drawings, as to effect a breaking of joints.

\Vhen a wheel of our present design is to be assembled upon a shaft which is already in position, we may employ sectional cheek plates 8, the joints between the same being then preferably arranged at right angles to thejoints between the sections 9, 10 of the hub proper, in the manner best shown in Figure 3. In other cases, we prefer to employ integral cheek plates and, in any event,'we find it advantageous to provide the hub sections, which are adapted to be secured together by means of the bolts 20, with a tapered, external surface 21, adapted to cooperate with a correspondingly tapered surface upon the interior of said cheek plates; and We also find it advantageous to provide notches 22, or other apertures, extending through the respective hub sections, these apertures corresponding with openings 23 in the cheek plates in such manner as to permit the use of tension bolts 24, passing therethrough and adapted to produce simultaneously a tension upon the spokes 7, by drawing their inner ends together, and a compression by means of the tapered sur face 21 upon the mentioned hub sections, effectively securing all of the mentioned parts rigidly together in such manner as to adapt the sameto a transmission of power.

Although we prefer to employ rivets 25, to secure the respective ends of the spokes, and optionally to secure also the abutting, inwardly inclined flanges which constitute a fin reinforcing the crown of our band -wheel, it will be understood that bolts, or

equivalent securing means, might be employed, or that electric welding might be resorted to.

The clips 14 may be so constructed as to reinforce the tug rim; and it will be noted that, as best shown in Figure 2, the respective spokes constituting a pair bolted together may be arranged to converge toward the center of a wheel; but the disclosed slight bending of the respective ends of each spoke into parallel planes is in any case optional.

Although we have described but one complete embodiment of our invention, it should be understood that various features thereof might be independently employed, and also that various modifications, in addition to those suggested, might be made within the spirit and scope ot our invention, as the same is indicated above and in the following claims:

. hat we claim is:

1. In a band wheel, a rim formed of a plurality of sections of channel iron each having an arcuate form and provided with inclined, channel-forming flanges, the inwardly inclined flanges thereof being secrued together to reinforce the crown of a wheel having a central, circumferential, rcinforcing fin formed of the inclined flanges secured together.

2. In a band wheel, a rim formed of a plurality of sections of channel iron each having an arcuate form and provided with inclined channel-forming flanges, the inwardly inclined flanges thereof being secured together to reinforce the crown of a wheel having inwardly extending flanges at its sides, and means for securing spokes thereto.

In testimony whereof we have signed our names to this specification.
